SEINE-PURSING APPARATUS.

SPEQIIIGATION forming part of Letters Patent No. 672,571, dated April 23, 1901,

Application filed December24, 1900. Serial No. 40,838. \No model.)

To all whom/it may concern: 1

Be it known that 1, JOHN SAVOY, a citizen of the United States of America, and a resident of the city of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Seine-Pursing Apparatuses, of which the following is a specification.

This invention relates to a seine-pursing apparatus.

One object of the invention is to produce an improved, simplified, durable, and efficient apparatus for drawing in the purse-line or bridle of a purse-seine and to so construct and organize the parts thereof that the purse-gear of the apparatus may be easily and readily operated by and the work divided between two operators without interfering with the indrawing, coiling, and storing of the purseline and without subjecting the operators to constant strain, as with apparatuses of this class of known construction.

A further object of the invention is to provide a seine-pursing apparatus including two} sheaves mounted upon a common shaft and walking-beam-actuated means in operative connection with said shaft and embodying: two alternately effective pawl-and-ratchet de,

vices operatively connecting the beam and sheave-shaft and adapted forim parting a substantially continuous purse line -indrawing movement to the sheaves through the oscillatory movements of the beam.

With these objects inview the invention consists in certain novel elementary features and in the special construction and organization of the several parts of the seine-pursing apparatus, substantially as hereinafter described, and more particularly pointed out in the claims.

In the drawings accompanying and forming part of this specification, Figure 1 is a persupport or dory and also showing a pursespective view, on a small scale, of a seinepurslng apparatus embodying thisinvention, showing the same in position on its floating seine with the bridle orpurse-line thereof in position to be hauled in by the pursing apparatus. Fig. 2 is a plan view of the seine-pursing apparatus on a relatively large scale minus the support and with a portion of the walking-beam handle-bars broken away, and

whole comprises a suitable support 13, shown as a boat, a pursing-gear frame, (designated in a general way by (3,) two horizontally-disposed driving and driven shafts 2 and 3, journaled for rotation in suitable bearings on the frame, two drums or sheaves 4 and 5, fixed to opposite ends, respectively, of the shaft 3, a walking-beam 6, pivotally supported substantially midway its ends intermediate the shafts 2 and 3 on an upright 7 of the frame 0 for movements in a vertical plane parallel to the vertical planes of said shafts 2 and 3, two alternatel y effective pawl-and-ratchet devices (designated in a general way by D and D, respec-,

tively,) operatively connecting the opposite ends of the walking-beam with the opposite ends of the shaft 2, an actuating-connector E between the driving and driven shafts,a davit 8, two purse-blocks 9 and 9, movably supported on said davit in alinernent with the peripheries of the sheaves 4 and 5, respectively, and two reactionary bight-forming levers 10 and 10, pivotally mounted on the frame C and having at their upper ends roll ers or projections 12 and 12, over which the free end of the purse-lines may extend to form a bight and hold the lines against retractive movements.

The purse-gear frame 0 of the apparatus, which may be of any suitable general con struction for supporting the several cooperative elements, comprises in the form thereof shown a suitable base-plate 13, adapted to be supported upon the seats or other portion of a carrier, such as a dory or fish-boat, and having relatively-separated vertically-disposed side walls 14 and 14.

The upright 7,upon which the Walking-beam 6 is pivoted, is shown in the nature of a bracket secured to the upper faces of the side walls 14 and 14 between the driving and driven shafts 2 and 3, respectively, the walkingbeam-supporting portion of said upright being shown located substantially midway be tween the adjacent faces of the side walls.

drawings the seine-pursing apparatus as a l The driving-shaft 2 is shown having its opposite ends in bearings 15 and 15 on the side Walls 14 and 14' and extending some what beyond the outer faces of said side walls.

The actuating means between the walkingbeam and driving-shaft is shown in the accompan ying drawings as two pawl-and-ratchet devices D and D, respectively. These pawland-ratchet devices are shown of duplicate construction. Therefore a detail description of one will suffice for both, the same char acters indicating the same parts of both pawland-ratchet devices. Each pawl-and-ratchet device in the preferred construction and organization thereof shown comprises a ratchetwheel 16, fixed to the shaft 2 and having plane peripheral bearing-faces 17 each side the ratchet-teeth 17', a gravitative dog or pawl-carrier 18, having a bifurcated end straddlingthe ratchet-wheel and having faces 18,adapted for engaging the plane peripheral portions 17 of said ratchet-wheel, two pawls I9 and 19, (shown in dotted lines in Fig. 3,)pivotally mounted on the pawl-carrier 18 in position for engaging the teeth of the ratchet-wheel, and a, suspending device 20, shown as a link .pivotally connecting the outer end of the pawl-carrier and the walkingbeam, the construction and organization of these parts being such that on a descending movement of that end of the walking-beam to which the particular pawl-carrier is connected, the pawls of this carrier being advanced one or more tooth-spaces into position to impart a rotative movement to the ratchet-wheel, andon anascending movement of the outer end of the pawl-carrier, due to the ascent of this end of the beam, the pawls will advance the ratchet-wheel and through the mediumof the actuating-connector E im-' part an lndrawingmovement to the sheaves i As will be understood .by reference to the drawings, the inner curved face of the pawlcarrier partly surrounds the periphery of the ratchet-Wheel, thus forming a fulcrum upon,

that is, a chain passes over two sprocketwheels, one of which is connected to the driv-.

ing-shaft and the other to the driven shaft; but it will be obvious that any suitable kind of actuating-connector between the two shafts may be employed, and the invention is not limited to the particular actuating-connector shown.

l The pawl-carrier shown in the accompanying drawings constitutes a most convenient means for carrying the pawls and insuring a ratchet-wheel-advancing movement thereof,

as said carrier issupported in placewholly by the ratchet-wheel upon'whichit operates, said carrier being moved about the axis of, said ratchet-wheel by the descending movement of the walking-beam in order to permit the pawls contained therein to take a fresh hold upon said wheel.

For the purpose of forming a, bight in the outer end of thepurse-line where it leaves the .sheaves 4 and 5 and to preventaccidental retractive movement of said line in case the ends of said lines are not-held I have provided two reactionary bight-forming devices, which I portions of which are disposed in proximity to and in alinement with the peripheral grooves in the sheaves 4 and 5, said bightforming devices being rendered reactionary or held with the rollers in close proximity to the peripheries of the sheaves by means of automatically eifective retracting devices 21 and 21, shown as spiral springs, which are fixed'at their outer ends to the levers 10 and 10' and at their inner ends to the side walls of the frameO, as shown most clearlyin Fig. 1.

Asa means for holding the upper runs of the ends of the purse-line in proper relation to the sheaves 4and 5, so that the ends of the line will, not become accidentally displaced or rideout of the grooves of said sheaves,.I

have provided a davit 8, which will be supported in any suitable manner,r(not shown,) having at the outer upper end thereof a block'- supporting bar disposed in parallelism with the driving-shaft 3, but located considerably in advance of the sheaves 4 and 5 and having at the outer ends thereof purse blocks or pulleys 9 and 9, disposed with the upper portions of their peripheries in substantially horizontal alinement with the upper portions of the grooves of the sheaves 4 and 5.

The springs 21 and 21 will have sufficient resistance to form purse-line-holding bights, but not a sufficient resistance to prevent the levers l0 and 10 being drawn downward by a pull on that portion of the line in advance of the said levers.

By providing walking beam actuated means for imparting indrawing movements to the sheaves it will be readily apparent that the work will be equally divided between the two operators working opposite ends of the walking-beam, for the reason that the pawl Ioo plane of the axis of the driving and driven evasvi where they will and in, no wise interfere with the coiling and storing of the ends of the 1 I purse-line.
